Zhiyuan Yang commented on TEZ-3386:
-----------------------------------
Yes, configuration of CartesianProductVertexManager slow start. We want it as a
general configuration but cannot pass it through UserPayload elegantly because
UserPayload contains some custom proto.
> Allow VertexManagerPlugin to get vertex configuration through context

> Currently there is no way to get vertexConf in VertexManagerPlugin.
> ShuffleVertexManager bypass this problem by passing configurations through
> user payload. But custom vertex manager plugin may need both configurations
> and custom user payload. It would make things easier to expose vertexConf to
> VertexManagerPlugin.
